"Before I called Maynor, I had 4 other companies give me an hvac replacement quote. Maynor was the 5th. I was very impressed with Mike who gave me the estimate. He exactly gave me the picture of what HVAC I was going to get and gave me choices and time to think about it. I decided to go with Maynor because of their reputation. NATE certified installers. I was right. Junior and Biri came to install my trane hvac with both heating and cooling. I also had zoning done. Very professional. Came on time at 7:30 and finished around 4 pm as I had zoning done the same day. Very impressed with the work done and the efficiency is to say the least. The next day, Jaime (supervisor) came to my house and reassured me that everything is working great. I appreciate the reassurance as it is a big investment. They are open 24/7 and they listen to your needs. Competitive quote and honestly lower than everyone else considering the quality of work. My heating was in the attic and the work was outstanding (I took before and after pictures and inspected everything they did). The zoning works perfect. If you are looking for quality, efficient and superb work, go for Maynor. You will never go wrong. I had researched, read all reviews and got estimates from 4 other big hvac installers. I was not convinced until I met Mike who was honest, detailed and organized. The only one who gave me the specific model number of the hvac I was getting and educated me regarding the different kinds of hvacs. Also, he did not push me to go with other brands like all the other 4 companies did. Maynor took care of me and I know they will take care of you too."

"Very well. Techs were held up but called to alert me and arrived exactly when they predicted. They were quick and efficient, and also very respectful of the home. They finished more quickly then anticipated. The HVAC system is quieter since they performed the work and I notice less dust. I could not be more pleased."

"Very good experience; professional and courteous. I called in the morning after finding I had no heat. Craig was out within hours to diagnose the problem. He had to order a part but was back next day to install. I would recommend them!"

Heating and Air Conditioning FAQs, answered by experts

You can buy R-22 refrigerant for your home air-conditioning system through your local AC repair specialist, who can also refill your R-22 system as needed. You may find that the cost of R-22 has gone up due to shortages as the EPA banned this refrigerant. Ask your pro to inspect your system for any leaks or issues.

If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.

Some HVAC systems tend to use R410A refrigerant, although if you have an older model it may be using R22. R22 is banned due to its harmful environmental and health impacts, and it is a sign that your AC unit is old enough to consider a replacement and the significant efficiency gains that could come with it.

A new HVAC system can increase your home's value by about 5% to 7%, which can translate to an added value of $2,500 to $3,000. The return on investment (ROI) can be around 30%, especially if you upgrade the entire system, including ductwork and insulation. Adding modern features like a smart thermostat can further increase your home’s value by making the heating and cooling systems more efficient and convenient. However, since a new unit can cost $10,000 or more to install, it's important to weigh the upfront cost against the potential increase in home value. For a specific assessment, it's best to consult a local AC installer.

Yes, it’s best to turn off an AC unit that’s blowing hot air to prevent system damage and avoid expensive energy bills. If you let the AC continue running, it will put more strain on the condenser coil and compressor. Plus, if the AC is blowing hot air because of a refrigerant leak, it can also lead to a frozen evaporator coil.
